Hard-Disk Spindle Motor Assembly Having a Spacer Ring
through which Nitrogen Gas or UV Light can Pass

Disclosed
here is a structure of spindle motor assembly aimed
to improve the assembly process by using a spacer ring through which
ultra violet (UV) light and nitrogen gas can pass to stimulate the
adhesion process.

As shown in
Fig. 1, in the spindle motor assembly process,
bearings are assembled to a shaft with UV adhesive agent which will
do its adhesion reaction after being
exposed to UV light. But in
the normal atmosphere the oxygen will hinder the UV adhesive from
doing its adhesion reaction promptly.
Accordingly, keeping the
adhesive to be hardened in nitrogenic environment, the adhesion
process can proceed more rapidly and more completely.

But it was
found that even after applying UV light and nitrogen
the adhesive in the gap between shaft and bearings was not hardened
completely. The major cause of the
problem can be thought to be that
the gap between shaft and bearings is so narrow that UV light and
nitrogen cannot reach the adhesive and stimulate the adhesion. To
make the best use of UV light and nitrogen the spacer ring which is
to be assembled between the top bearing and bottom bearing should
have the shape that let UV light and nitrogen pass in more easily.

In this
invention it is proposed that the spacer ring be
redesigned as the following four new types:
